Overexpression of the Tomato Pollen Receptor Kinase LePRK1 Rewires Pollen Tube Growth to a Blebbing Mode [PDF]

, 2014
The tubular growth of a pollen tube cell is crucial for the sexual reproduction of flowering plants. LePRK1 is a pollen-specific and plasma membrane–localized receptor-like kinase from tomato (Solanum lycopersicum). LePRK1 interacts with another receptor,

Potential for gene-flow from cultivated Irish grasses and cereals [PDF]

, 2009
End of project reportThe importance of gene movement from cultivated plants has been highlighted in regard to minimising the movement of seed and/or pollen between GM and non-GM crops (i.e. gene flow). Although ryegrass covers in excess of 90% of Ireland’

Molecular cloning and transcriptional activity of a new Petunia calreticulin gene involved in pistil transmitting tract maturation, progamic phase, and double fertilization [PDF]

, 2013
Calreticulin (CRT) is a highly conserved and ubiquitously expressed Ca2+-binding protein in multicellular eukaryotes. As an endoplasmic reticulum-resident protein, CRT plays a key role in many cellular processes including Ca2+ storage and release ...
